Suns out, BUNS out! Kendall Jenner left little to the imagination when she wore the teeny-tiniest, little green bikini on vacation in St. Barts. Not only was the model’s sick midriff on display, but her whole booty was out!

Kendall Jenner joined her sisters on a yacht in St. Barts for some vaca fun and by the looks of her tiny bikini, she was definitely anticipating a nice tan (with minimal tan lines). The 19-year-old stunner wore thong bathing suit bottoms, so it’s safe to say her booty got plenty of color — see the pic of Kendall’s scandalous bikini!

“Kendall is really jealous of Kylie’s freedom when it comes to her hair,” an insider told us. “She can go blue for a while, blonde, put it in cornrows, dreadlocks and cut it however she likes. Kendall has been told that designers and advertisers really like her long straight black hair and that she shouldn’t mess with it. She won’t get the top notch modeling jobs if she has bleached or blue hair.”
